Thomeer Parameters and Petrophysical Rock Types: A Thomeer hyperbola is fit to the HPMI data by optimizing on the Thomeer Parameters G1, Pd1 and BV1 for the first pore system and G2, Pd2 and BV2 for the second. The following image relates the Thomeer hyperbola (dashed black line) to the Capillary Pressure Curve (solid red line). Petrophysical rock types (PRTs) can be defined as objects in the three dimensional space defined by Thomeer pore system parameters. Classifications in the Thomeer parameter space must also be accompanied by relationships to convenient well bore measurements (commonly well logs) and geologic parameters to create economic value in the petroleum business. 2021-02-07 · Thomeer Parameters and Petrophysical Rock Types: A Thomeer hyperbola is fit to the HPMI data by optimizing on the Thomeer Parameters G1, Pd1 and BV1 for the first pore system and G2, Pd2 and BV2 for the second.

Thomeer parameters

Thomeer parameters for a multi-pore system of a Thomeer model are determined by evaluating an objective function that measures the mismatch Thomeer methodology was used for Static Rock Typing analysis, utilizing the extensive available Mercury Injection Capillary Pressure Data (MICP) to capture the complexity of the M carbonate reservoir, and the Thomeer parameters (G – shape factor, Bv – Bulk Volume and Pd – entry pressure) were derived for every pore mode of these selected MICP plugs. Pore structure characterization and permeability estimation with a modified multimodal Thomeer pore size distribution function for carbonate reservoirs Thomeer also evaluated both the significance and accuracy of determination of these parameters. Values were determined from capillary-pressure curves on 144 parameters. Values were determined from capillary-pressure curves on 144 diverse rock samples and correlated with air permeabilities measured on the same samples.

As a part of this process, detailed core to log integration, permeability prediction modelling, and well log quality control steps are utilized. Grain Size distribution Parameters The parameters of a millimeter plot or a phi plot can be determined from the following formulas (after Folk and Ward 1957 and Jorden and Campbell,1984.). ϕx is a grain size expressed in phi(ϕ) units such that x% of the sample is larger than this grain size. (Note: There are also other formulas to Examples of Thomsen's parameters for various choices of EMT are displayed in Figure 2.

The same calculation was performed using the Thomeer hyperbole parameters of the rocktype. representatives for all the number of groups.

For a practical description of 6 Jun 2019 The shape of this function is determined by three Thomeer parameters: - Pd is the “Minimum Entry Pressure” related to the largest pore throat;. Thomeer parameters relate to the controlling parameters of Gaussian density function. 根据Thomeer参数提出了三种渗透率模型，并与以前的模型进行了比较。 Not all curves, however, are hyperbolic and suitable for assignment of G values. Thomeer (1960) showed graphically that a relationship exists among air weakness related to the Thomeer curve fitting procedure: it is sensitive to heterogeneous pore- throat distributions, resulting in unrealistic Thomeer parameters. (e.g., Swanson parameter, area under the curve, threshold entry pressure, capillary pressure at different mercury saturations, Thomeer parameters, Brooks and parameters in the Gaussian density function relate more directly and intuitively to pore- system attributes than the parameters included in Thomeer's derivative.

The parameters are normally derived from the mercury/air capillary-pressure curve but may also be approximated from a petrographic analysis of thin sections. study suggests that the Thomeer parameter equivalent to largest pore-throat radius, could be used as cut-off parameter for rock/pore typing of the complex, multi-modal formations in Edvard Grieg field, but future studies are needed to confirm. The rest of this thesis is organized as follows.

A prediction model for it is presented based on capillary pressure model, and the J-function prediction model is a power function parameter in volumetric studies where it is used to calculate fieldwide saturation-height relationships from core and log information. It is also employed to infer the free water level (FWL) from oil transition zone saturation-height relation when valid pressure gradient data for both oil and water legs may not be available.

track it aims to highlight a set of derivable parameters of mercury capillary curves using the Thomeer-method. Since the widely used mercury capillary pressure It may be expected that parameters in such a relation can then be used to describe differences in pore geometry of these samples.
